The invention relates to hair care compositions comprising an effective amount of a condensation polymer having at least one, optionally quarternized or protonated, dialkylamide end-group connected through the polymer backbone to a unit derived from an alkylamide, the connection comprising at least one ester linkage.

In hair care products the use of polymers is gaining more and more importance, for example to improve the rheological behaviour of the product or to enhance the adhesion of other ingredients to the hair. Thus, there is a growing need for polymers suitable for use in hair care compositions fulfilling the manifold requirements posed on such polymers in regard of availability, easy handling and/or cost/performance.

In hair care preparation for example film forming polymers are used e.g. as conditioning agent in order to improve the combability, the shine and the visible appearance of the hair as well as to give the hair antistatic properties.

Commercially available polymers for hair care such as hair styling or conditioning polymers are e.g. copolymers of vinyl acetate and crotonic acid, copolymers of methyl vinyl ether and maleic anhydride, copolymers of acrylic acid or methacrylic acid with other monomers, polyurethanes, N-vinylpyrrolidone and silicone polymers.

The aim of the invention was to provide easily available, cost efficient hair care compositions comprising an effective amount of a condensation polymer having an, optionally quarternized, dialkylamide end-group connected through the polymer backbone to a unit derived from an alkylamide, the connection comprising at least one ester linkage. The hair care composition should fulfil a variety of requirements such as exhibiting low stickiness, lack of powdering or flaking, preferably being clear, transparent and glossy. Additionally, hair care compositions should offer excellent performance e.g. in regard of good film formation, good holding power, high level of style retention, prolonged curl retention, improved combability, and should be easily removed upon washing the hair with shampoo or soap.

Polymers suitable for the incorporation into hair care compositions should exhibit a excellent heat stability, very good solubility, compatibility with cosmetic bases, pH stability in the range of 4 to 9, processability into a variety of products, compatibility with other ingredients and with the packaging materials and should be free of color and be of neutral or pleasant odor and have a low volatility.

It has now surprisingly been found that condensation polymers having at least one, optionally quarternized, dialkylamide end-group connected through the polymer backbone to a unit derived from an alkylamide, the connection comprising at least one ester linkage (in the following referred to as condensation polymer) are especially suitable for the preparation of hair care compositions.

It has also be found that they can be used as conditioning agents, strengthening agents, film forming agents, surfactants, anti-static agents, moisturizers, emulsifiers or hair styling agents in hair care compositions.

If the components used in hair sprays or hair foams according to the invention are water dispersible, then they may be in the form of micro dispersions with particle sizes of usually 1-350 nm, preferably 1-250 nm. The solid content of such preparations is typically in the range of 0.5 to 20 wt. % of the total weight of the preparation.

The mixture was slowly heated to 180° C. and ½ h after the start, 236.1 g 2-methylamine ethanol was added and 1½ h later vacuum was applied to remove the reaction water. After 5 h the mixture was cooled and a glassy polymer was obtained.

EXAMPLE 14 Styling Performance

Determination of the styling effect of hair care compositions according to the invention comprising quaternized condensation polymers. The styling properties are determined by measuring the stiffness of hair tresses after treatment with a leave-on formulation (@ 1% active concentration in water/ethanol 80:20).

Hair tresses: Double bleached Caucasian hair, remis, 2 cm wide, 20 cm length, Kerling Gmbh.

Experimental design: Each hair tress was immersed in 20.0 g of the formulation in a closed glass cylinder. The cylinder was shaken horizontally for 1 min. The tresses were then removed, detangled and combed 20 times in a downward motion to remove all excess solution. The tresses were then allowed to dry overnight in ambient conditions. The stiffness was evaluated manually. The stiffness is summarised in the table below. The scale goes from + to +++ whereas +++ expresses very high degree of stiffness.

As can be seen from the table, the quaternized hybranes lead to enhanced stiffness relative to placebo treatment which can be advantageously used in styling products.
